From: Masahisa Kojima Date: Mon, 3 Jul 2023 06:08:45 +0000 (+0900) Subject: efi_driver: fix duplicate efiblk#0 issue X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=06fc19ca4de943827f5aa026f7aa9c3a05411677;p=u-boot.git efi_driver: fix duplicate efiblk#0 issue The devnum value of the blk_desc structure starts from 0, current efi_bl_create_block_device() function creates two "efiblk#0" devices for the cases that blk_find_max_devnum() returns -ENODEV and blk_find_max_devnum() returns 0(one device found in this case). This commit uses blk_next_free_devnum() instead of blk_find_max_devnum().
